I got my pin a couple days before I got the bill.
The pin is about 2" wide and 1.75" high. It's nice and a lot bigger than I thought it would be. But then I'm not a Pin Trader, so I don't know what these things normally look like.
It looks like the image from the application site--red "card" that says "Day 1, 2003, Disney's Visa Card" with black Mouse Ears peaking out behind it. Comes in a nice little plastic box. And has a mouse ears pinback.
Also, the envelope says "Bank One" on the return address if I remember correctly.
